labs.laberrors.LabError: Script projects-concept not in course library gl006

An error has occurred. For more details, run: lab logs projects-concept 

Steps to reproduce:

Users are unable to start the "projects-concept" lab due to missing modules for the course 'gl006'. The system throws a ModuleNotFoundError indication that the module 'gl006' could not be found, followed by a LabError stating that the "projects-concept" script is not present in the course library 'gl006'. This issue needs to be addressed to ensure the lab script runs correctly.

I am able to reproduce the issue.  Please review
